Abstract
Background
‘Neuromarketing’ is a term that has often been used in the media in recent years. These
public discussions have generally centered around potential ethical aspects and the public fear
of negative consequences for society in general, and consumers in particular. However,
positive contributions to the scientific discourse from developing a biological model that tries
to explain context-situated human behavior such as consumption have often been neglected.
We argue for a differentiated terminology, naming commercial applications of neuroscientific
methods ‘neuromarketing’ and scientific ones ‘consumer neuroscience’. While marketing
scholars have eagerly integrated neuroscientific evidence into their theoretical framework,
neurology has only recently started to draw its attention to the results of consumer
neuroscience.
Discussion
In this paper we address key research topics of consumer neuroscience that we think are of
interest for neurologists; namely the reward system, trust and ethical issues. We argue that
there are overlapping research topics in neurology and consumer neuroscience where both
sides can profit from collaboration. Further, neurologists joining the public discussion of
ethical issues surrounding neuromarketing and consumer neuroscience could contribute
standards and experience gained in clinical research.
Summary
We identify the following areas where consumer neuroscience could contribute to the field of
neurology:
First, studies using game paradigms could help to gain further insights into the underlying
pathophysiology of pathological gambling in Parkinson’s disease, frontotemporal dementia,
epilepsy, and Huntington’s disease.
Second, we identify compulsive buying as a common interest in neurology and consumer
neuroscience. Paradigms commonly used in consumer neuroscience could be applied to
patients suffering from Parkinson’s disease and frontotemporal dementia to advance
knowledge of this important behavioral symptom.
Third, trust research in the medical context lacks empirical behavioral and neuroscientific
evidence. Neurologists entering this field of research could profit from the extensive
knowledge of the biological foundation of trust that scientists in economically-orientated
neurosciences have gained.
Fourth, neurologists could contribute significantly to the ethical debate about invasive
methods in neuromarketing and consumer neuroscience. Further, neurologists should
investigate biological and behavioral reactions of neurological patients to marketing and
advertising measures, as they could show special consumer vulnerability and be subject to
target marketing.

Background
Scientific development in recent years is characterized by an expansion in the application of
different and multidisciplinary research modalities in order to answer the various questions of
a given scientific field. Of particular interest is the explosion in the use of neuroscientific
methods, ostensibly to better understand human behavior in various contexts. This has led to
the creation of the term ‘neuroculture’ [1], to refer to new scientific branches combining
neuroscience with other scientific branches, arts or humanities, examples of this phenomenon
include neurophilosophy (e.g. [2]) or neurotheology (e.g. [3]). Similarly, but in an even more
pejorative sense, Tallis [4] coined the term ‘neuromania’ to refer to a headlong rush by
seemingly all fields of study to embrace neuroimaging, and explain all human phenomena in
terms of brain activity. Yet while Tallis [4], and others critical of the embracing of
neuroimaging by various fields of study present powerful caveats against the unquestioning
acceptance that human life in all its complexity can be reduced to brain activity, it is
undeniable that – when applied properly – neuroimaging has much to offer as an addition to
existing scientific tools, techniques, and frameworks [5].
Of particular interest is brain imaging research in the economic and business disciplines.
Indeed, economists were amongst the first social scientists to recognize the potential of
neuroimaging, with the development of neuroeconomics [6-12]. Soon after the first
neuroeconomic papers had been published, marketing scholars discovered the potential of
neuroscientific methods as a new research approach beside the classical qualitative and
quantitative methodological spectrum in the social sciences. Early on in the field’s
development, the term ‘neuromarketing’ research was suggested in order to categorize studies
in the interdisciplinary field between economics, psychology, biology and medicine [13].
However, in the ensuing decade, multiple definitions of neuromarketing appeared to develop,
even as neuroscientific and radiological advances expanded the array of tools available to
researchers in this fledgling field [14-16].
Generally speaking, neuroscientific methods are used to study consumer behavior and the
decision-making processes in purchasing acts [17], to better understand psychological
phenomena and emotions in purchase decisions, as well as provide a more comprehensive
assessment of the efficacy of marketing phenomena like advertising, consumer competitions,
and product placement, by analyzing the underlying neurobiology [18]. Such studies are per
se purely academic, although they clearly try to develop and derive recommendations for
practical marketing. Independently, there are many businesses offering neuroscientific
methods under the umbrella term ‘neuromarketing’. Often, the services offered by such firms,
and their explanatory power, appear exaggerated in advertising and one only has to have a
cursory understanding of neurophysiology to see that many of the outlandish claims made in
the popular press about how neuroimaging can identify complex phenomena such as ‘love’,
or behaviors such as purchasing, to be far overblown [19]. A recent study identified over 150
such companies [20]. An analysis of 16 companies identified through an internet search
revealed that 5 of them offered fMRI, 9 EEG and 12 Galvanic-Skin response and other tests
of the autonomic nervous system as methods [21].
Of course, the application of neurophysiological methods as adjuvant instruments to
behavioral data in marketing research is not entirely new, but has attained media presence in
last decade by the use of easily-discussed imaging methods such as functional magnetic
resonance imaging (fMRI), and the special influence that brain images have on non-
neuroscientists [22]. In 2008, Hubert and Kenning reported more than 800,000 Google hits
for the term ‘neuromarketing’ [23], and in 2012, the same search yields over 1.4 million hits,
underlining the continuing interest in this topic.
This development has further led to a discussion about ethical aspects of neuromarketing not
only in scientific communities, but also in the general media [24,25]. Suddenly, journalists
and by extension consumers appear to fear that market researchers might be able to analyze
their private thoughts and emotions during purchase, and even be able to influence them to
buy (e.g. [26]). This fear is not new though, and appears to be broadly similar to earlier fears
over subliminal advertising (for an overview see [27]), even though this idea was later
debunked (e.g. [28]). Of course, traditional market research has always been interested in
analyzing and predicting purchase behaviors, but the advent of high-profile neuroimaging
studies seems to have driven an explosion in public attention. Given the lack of knowledge on
how experimental studies including marketing research are in fact performed, the general
public are easily frightened. These ethical concerns have been further inflamed by the
foundation of more and more enterprises (especially in the United States) offering
neuromarketing as a service.
Unfortunately, debates over neuromarketing tend to lack a differentiation between scientific
and commercial for-profit applications [29]. Especially in the public ethical discussion, it is
important to distinguish academic studies that use neuroscientific methods from those purely
for the purposes of commercial marketing. It is not taken into consideration, that scientific
studies often focus on the consumer’s point of view, while commercial ones try to apply
findings in order to sell a product. In particular, human beings do not act in a vacuum, and
human behaviors are almost always context-laden. Much human behavior occurs within a
consumption context, and it has been argued that incorporating such a context to
neuroscientific work can also be of significant benefit [5,19,29] Academic studies in
neuromarketing have a highly interdisciplinary character. Knowledge from marketing
management is tied together with psychological knowledge and different medical fields
(above all neurology, psychiatry and radiology). As the general media mostly address
commercial marketing when reporting about neuromarketing, it is essential to decouple these
two entities and to controvert the mechanistic public opinion about the brain-behavior
relationship by terming the scientific branch ‘consumer neuroscience’ [14,19,20]. A similar
debate about adding the ‘neuro-’prefix to other behavioral sciences and the consequences of
this ‘neuromania’ has been led lately by several authors in leadership research [14,19,30].
Furthermore, among scientists and journalists, there is an ambiguous view of neuromarketing.
Beside a group of advocates, who represent the opinion that neuromarketing would lead to
product improvement and therefore is beneficial for consumers [24,25], there are numerous
critics [31-33]. For example, an editorial in ‘Nature Neuroscience’ stated that:
‘Neuromarketing is little more than a new fad exploited by scientists and marketing
consultants to blind corporate clients with science.’ [34,35]. Hence, we strongly suggest a
discussion of both what neuromarketing can and cannot do, and also what it should and
should not do, involving experts from both business and neuroscientific research as well as
ethicists and philosophers. Willingham and Dunn [36] elaborated ways of integrating brain
imaging data into social psychology theory. A similar synthesis of brain imaging data and
marketing theory still has to be developed. The results of such a discussion could then be
presented to the public and would lead to an informed public view of neuromarketing.
Research in the field of what was termed above ‘consumer neuroscience’ has on the other
hand generally been positively accepted within the academic community. However, while
marketing scholars have eagerly integrated neuroscientific evidence into their theoretical
frameworks, medicine is reluctant to adopt the results of consumer neuroscience. First
attempts to transfer knowledge between neuroeconomics and psychiatry have been recently
published [37], but it is clear that a joint discussion of how knowledge gained in ‘consumer
neuroscience’ can contribute to a broader field of science, including especially biology,
neuroscience, psychiatry and neurology, is still scarce. Despite this, findings from consumer
neuroscience studies are significantly contributing to all behavioral sciences, especially by
focusing on the interaction of cognitions and emotions in human behavior [38-40].
Discussion
As such, the results of consumer neuroscience research can be fruitful for both scientific and
clinical neurology for a number of reasons. Behavior has always been a major topic in
neurological and psychiatric research and has led to the subspecialty of behavioral neurology,
which manages the diagnosis of, and therapy for, behavioral symptoms of neurological
disorders, e.g. dementia, depression, psychosis, anxiety, obsessive-compulsive disorder,
attention deficit/hyperactivity disorder, autism, and agitation through neuropsychological and
neurophysiological methods (including neuroimaging) [41]. Further, human behavior and the
activities of daily living (ADL) are included in several diagnostic classifications and rating
scales (e.g. ICD-10, DSM IV, Schwab and England activities of daily living scale). Consumer
behavior research is considered a behavioral science and studies humans in these daily
activities and in real-world settings. Neuroeconomics and consumer neuroscience investigate
neural correlates of human behavior related to job performance, social and consumption
behavior. Behavioral neurology may obtain a more comprehensive understanding of human
behavior by incorporating insights from interdisciplinary approaches like consumer
neuroscience, that analyze behavior relevant to the real world (see also [42]).
Consumer neuroscience has so far studied a large number of neurobiologically-oriented
topics, and as such a complete review would be out of our present scope. Rather, we chose to
concentrate on three topics that appear to be of most relevance to neurologists. We focus on
(1) the reward system and its relations to brand preference and decision-making in
purchasing, as it plays an important role in several neurological diseases and their behavioral
symptoms. Further, we explore (2) the neurobiology of trust, as it is the basis of every
patient-physician relationship and therefore of special interest to any physician. Finally, we
include a discussion of (3) the ethical aspects of neuromarketing, since they dominate public
debate in this field.
The three key topics will be briefly summarized and discussed in terms of their relevance to
neurology in subsequent sections of this paper. In doing so, we try to make clear that the
ecologically-valid research settings available in marketing research contexts can add
significantly to neurology. As such, on the one hand, the findings of consumer neuroscience
that we present in this paper might initiate further neurological and clinical research in an
interdisciplinary setting. On the other hand, neurologists might be increasingly interested in
joining the public discussion about neuromarketing and its ethical concerns. Both outcomes
would be of significant benefit to both scientific research and general social progress. The
paper aims at providing the basis for an enhanced two-way discussion instead of the one-way
path currently active.
Consumer neuroscience and the reward system
Two major brain systems are considered to be fundamental to almost all human behavior; the
reward approach (pleasure-seeking) and the loss/pain avoidance systems [43,44]. The
neurobiology of the reward system is based on the meso-limbic pathway, which extends from
the ventral tegmental area (VTA), through the nucleus accumbens (NACC) and the limbic
system, to the orbitofrontal cortex (OFC), while anticipation of loss, pain or punishment
activates the insula [45-48], for a review see [49,50]. Differential roles for these brain areas
have been recently detected and are summed up as the ‘Schultz Theory’ [51]. The nucleus
accumbens seems to play a role as an integration site, receiving impulses from the OFC,
which represents reward expectations, the amygdala (responsible for reward conditioning),
and dopamine neurons, all of which play a role in reward prediction. The VTA and substantia
nigra show a high density of dopaminergic neurons. Brain stimulation studies have shown
that activation of these dopaminergic systems leads to feelings of ‚well being’ [52]. Outputs
of the striatum to the VTA code for mismatch between predictors and reward.
Behavior is closely related to the reward system. In animals, basic rewards like food, drink
and sexuality are predominant goals to be achieved through behavior. However, in humans
more abstract forms like financial and social rewards (success, social status, culture etc.), or
drugs that interfere with the neurophysiology of the reward system, are also main targets. In
addition, certain physical objects, like cars [53] or money [54] can be rewarding. There is a
considerable inter-individual variance in the sensitivity to reward stimuli [55]. In classical
marketing as well as in consumer neuroscience, major research topics include the purchasing
act and how this behavior is influenced, for example by the preference for a certain brand,
although how brands effect consumer decisions is still a matter of debate [56-58].
The neurobiological basis of brand preference has been a research topic from the beginning
of consumer neuroscience, and remains so today. The dorsolateral prefrontal cortex (DLPFC)
is thought to be prominently active in the representation and integration of goals and reward
information [59] and might initiate, through connections to the mesolimbic system, reward-
motivated behavior [60]. The function of the ventromedial prefrontal cortext (VMPFC) is
however still debated in neuroscience literature. Most authors suggest an important role in
decision-making, especially in choice tasks [61].
In consumer neuroscience the VMPFC is studied in the context of brand preference. Paulus
and Frank [62] postulated that this region plays a key role in preference judgments, while
other authors presented data challenging this hypothesis [63]. McClure et al. [64] examined
the brand preference for Pepsi and Coca-Cola drinks by means of fMRI. Finding that in blind
tastings, no difference between the response in the brain appeared. However, in open tastings
(when subjects could see the brand), limbic structures like the hippocampus and the DLPFC
showed enhanced activity, presumably according to brand preference. One conclusion of this
experiment is that preference is processed in different brain areas depending on the source of
information: the VMPFC is active when preferences were based on sensory information only
(taste), while the hippocampus, the DLPFC and the midbrain showed enhanced response
when judgments were based on both sensory inputs and the brand. This study, among others,
suggests the importance of emotionalizing for the success of a brand [54] and hints at
subconscious and purely emotional aspects involved in consumption behavior.
Purchasing is a behavior at least partly determined by the reward system. The pros (reward of
buying) and cons (displeasure of paying) have to be weighed up against each other in the
sense of a hedonic competition between pleasure and pain [65]. Purchasing acts are preceded
by an activation of the nucleus accumbens, which correlates with product preferences, while
high prices can lead to an increase of insula activation in the sense of an anticipation of loss
[66]. An increase in the BOLD (blood oxygen level dependent) response measured by fMRI
in the insula cortex can further precede a negative product choice [66-70]. Thus, preferred
brands can be seen as a reward stimulus, and may impair strategic reasoning, probably by a
reduced activity of the DLPFC [71]. These preferred brands also seem to activate the reward
system more than others [72], while the price of a product directly affects neural reward
signals through an increased expectation [73]. Read in conjunction with the previously
mentioned article of Knutson et al. [66] a high price can therefore either lead to an
anticipation of loss, or to a reward through a high anticipation of utility.
A paradigm commonly used in animal research is conditioned preference. Here, a preference
for a neutral stimulus is created by rewards. Johnsrude et al. [74] adapted this approach to
human volunteers with unilateral anterior temporal lobe resections, and by doing so created
evidence for a role of the amygdala in reward conditioning. A relevant question in this
context concerns the degree to which unconscious stimuli can influence behavior [75].
Although there are theories regarding how brand preference is built over time [76], a
functional brain imaging study about how brand preference can be conditioned by marketing
tools such as advertising has, to the best of our knowledge, not been realized yet. While such
a study is certainly challenging concerning the experimental design, it would be an interesting
field for future research. In fact, recent fMRI-studies [77,78] indicate celebrity endorser
credibility has a modulating effect on product preferences and memory. Celebrity
endorsement is a widely used technique in advertising, hence the results of these fMRI-
studies could build the basis for a more detailed investigation of advertising’s effects on both
product and brand preferences.
To sum up, through the study of purchasing acts and brand preference, general and consumer
neuroscience have gained significant knowledge about the reward system, frontal brain
regions and their relevance to decision-making. Although there are lesional studies on brand
preference and purchasing behavior, a research gap seems to exist, as how neurological
diseases affect behavior and decisions in this context.
Implications for neurology
The reward system is related to a set of behavioral anomalies that are frequently found in
neurological diseases, like impulsive-compulsive disorders, including pathological gambling
and compulsive buying. As there are both neurologists and consumer neuroscientists involved
in research of these behavioral patterns, we think that these contexts offer an opportunity for
interdisciplinary research. Pathological gambling is characterized by a loss of control over
gambling, deception about the extent of one’s involvement with gambling, family and job
disruption, theft, and chasing losses, or the effort to win back money lost while gambling
[79]. It is frequent in Parkinson’s disease [80], restless legs syndrome [81], frontotemporal
dementia [82], epilepsy [83] and Huntington’s disease [84] and might be the consequence of
a neurodegenerative or iatrogenic impairment of reward pathways [85,86]. Pathological
gambling is also associated with a reduced activation of the mesolimbic reward system in
functional brain imaging [87]. It has already been suggested that psychiatry should adopt
findings from neuroeconomics, especially in pathological gambling. ‘…[E]xperimental
paradigms derived from NE [neuroeconomics], such as economic exchange games, can be
usefully applied to understand psychiatric disorders…’ [88]. We argue that behavioral
neurologists should investigate patients suffering from a neurological disease with a higher
incidence of pathological gambling using game paradigms of neuroeconomics and paradigms
involving brands and purchasing acts of ‘consumer neuroscience’ to learn more about the
underlying pathophysiology.
Compulsive buying is a highly debated disorder in the psychiatric field, as its classification as
a behavioral addiction or an impulse control disorder is still unclear [89]. Compulsive buying
is defined as ‘a tendency to be preoccupied with buying that is revealed by repetitive buying
and a lack of impulse control over buying’, with an incidence of 5.8% in the United States
[90]. It is considered to be related to the reward system [91]. A higher incidence for this
behavior has been reported in patients suffering from Parkinson’s disease [80] and
frontotemporal dementia [92]. Further, there is a co-occurrence between depression and
impulsive-compulsive buying [93], which supports the theory of an impaired reward system
in depressed patients [94]. A recent consumer neuroscience study was able to show a
difference in the activation of the reward and loss/pain avoidance system between compulsive
and non-compulsive buyers. The former showed a higher activity in the nucleus accumbens
and a lower activation of the insula during the presentation of a product and its price than
non-compulsive buyers [95]. A study about the responsiveness to brands and advertising of
neurological patients suffering from compulsive buying behavior could further advance
knowledge in behavioral neurology.
Trust
Trust is a basic human phenomenon, essential for humans if they are to live among unknown
others, and therefore is vital for the functioning of modern societies [96,97]. Multiple
definitions of trust exist, but most somehow refer to trust as a behavior [98]. Trust behavior
involves the voluntary placement of resources at the disposal of a trustee with no enforceable
commitment from the trustee. This situation can either be beneficial for both sides, if the
trustee reciprocates, or lead to loss for the trustor if the trustee is opportunistic. Trust thereby
involves the risk of betrayal. Recent research indicates that distrust is unlikely to be simply
the absence of trust, but a distinct phenomena itself, which makes it possible to have a certain
degree of trust and distrust at the same time [99]. However, one of the most challenging tasks
in research involving human behavior is the operationalization of trust/distrust. In
neuroeconomic research the trust game and the evaluation of trustworthiness of faces are
common methods [100,101]
a
.
A detailed review of literature on trust is well beyond the present scope. In what follows then,
we give an overview of biologically-orientated literature on trust. For greater detail we refer
readers to a number of reviews that can be read in conjunction with the present piece (e.g.
[102-104]).
Trusting an unknown person requires an individual to perform a number of stepwise
evaluations. Each of these steps is associated with distinct brain areas.
• Trustworthiness evaluation: By visual perception of key anatomic features of the
other person’s face his or her trustworthiness is assessed. This can lead to uncertainty,
ambiguity or fear. During this process the amygdala and the insula cortex show
activation in fMRI scans [105-107].
• Prediction of the other person’s future action: At this stage, questions as to the
likelihood of trust reciprocation, deception, prior knowledge of this person, or prior
experience of trusting unknowns are evaluated. Here, theory-of-mind regions such as
the paracingulate and the medial prefrontal cortex, as well as memory regions (e.g.
amygdala and hippocampus) are active [108,109].
• Calculation of future reward: Here, the neurobiological reward system is relevant, as
the individual assesses the likely reward of their trusting behavior. This system is
discussed above (see also e.g. [106,107,110]).
• Processing of cognitive conflict is associated with activation in the anterior cingulate
cortex [104-106]. In trust situations this area is active, because the risk of betrayal and
the possible reward of a beneficial outcome have to be weighed up against each other.
Besides these specific brain areas, several neurotransmitters and hormones modulate trusting
behavior (for a review see [104]). Oxytocin, a neuropeptide that plays an important role in
social approach behavior, has been found to be associated with trustworthiness [111] and to
increase trust when administered intranasally [112]. Oxytocin leads to an increase of
dopamine levels [113], and dopamine is thought to be the main neurotransmitter of the
reward system [114], which plays an important role in trust (see above). Recent literature
suggests, that the prosocial effects of oxytocin might be context dependent in the sense, that
oxytocin acts predominantly on behavior towards members participating in a group in
contrast to out-group members [115-117]. Cortisol, a stress hormone, has only recently been
associated with trust and seems to play an antagonistic role to oxytocin [118]. Further, a
gender difference in trust has been proposed, and several surveys show that men trust more
than women, (e.g. [119]). Women also exhibit different brain activation patterns in a
trustworthiness evaluation task [120], and trust related brain areas (e.g. caudate nucleus)
differ in size between the genders [121]. Furthermore, gender dimorphisms for distrust have
been reported [122].
In marketing research, consumer trust is a key focus. The perceived trustworthiness of brands
is seen as the main basis for brand loyalty, which indicates a certain purchase consistency and
brand performance [123,124]. Furthermore, research involving trust in advertisements, as
well as trust in online environments (e.g. offers and websites) has flourished in recent years
[120,125-127]. Trust in relationships between marketing operatives (e.g. industrial purchasers
and sellers) is also a key theme in research [128,129]. However, even though trust is
commonly cited as a major research topic in consumer neuroscience (e.g. [29]), experimental
data in this area has mostly been acquired by scientists involved in neuroeconomics and
decision neuroscience (e.g. [130]).
Implications for neurologists
In recent years, economically-orientated sciences have shed light on the neurobiology of
interpersonal trust through questionnaires and gaming paradigms. Medical research at the
same time has focused on the important role that trust plays in the patient-physician
relationship, as health outcomes of several diseases have been shown to be associated with
trust in physicians [131,132]. Several studies also showed a positive impact of a patient’s
trust in physicians on patient satisfaction, therapy adherence and continuity of care [133-135].
Being comforting and caring, demonstrating competency, answering questions, and
explaining diagnosis and therapy to the patient has been shown to increase trust [136].
Multiple neurological diseases lead to an impairment of trust-relevant brain areas and/or a
disequilibrium of associated hormones. Depression leads, on the one hand, to structural
changes in the caudate nucleus and other trust-related brain areas and, on the other hand, to
hypercortisolemia [137,138], and should therefore theoretically impair trust on the basis of
these two mechanisms. As the reward system is part of the brain’s trust network, it seems
plausible that diseases affecting the dopaminergic pathways could also impair trust behavior.
Further, there are several neurological diseases affecting frontal brain regions, e.g.
frontotemporal dementia and other neurodegenerative diseases as well as certain types of
epilepsy, that could lead to lower trust. Empirical behavioral data (e.g. using the trust-game
or paradigms, where trust of sale-offers and brands is assessed) is needed to test this
hypothesis and can be seen as an opportunity for a fruitful collaboration of neurologists or
psychiatrists with researchers in consumer neuroscience. A transfer of knowledge would
certainly be profitable for both sides, as it would lead, on the one hand, to new insights into
the neurobiology of trust. On the other hand, neurologists could identify diseases leading to
lower trust in physicians and deduce guidelines to improve communication with, and therapy
adherence of, these patients.
